To all whom'it may concern:

'Be it known that I, Tnnouoan D. LAY- MAN, a citizen of the UnitedStates,' residing at Indianapolis, in the county-of Marion and State ofIndiana, have invented, a new and useful Detachable Gun M'agazine', ofwhich the followingis a specificatiomreference being had to theaccompanying drawings and to the letters and figures, of referencemarked thereon.

This invention relates to cartridge ma 'azines and means for detachablyconnecting the magazines to guns,'more especially to auto-loading'riflesin which high power eartridges of thebottle neck type are used, theinvention having reference more "particularly to a magazine and atrigger plate that are designed to be readily applied to existing riflesafter removing unsatisfactory corresponding parts of the rifles, theimproved parts bemg applicable also to new rifles'or guns of var oustypes:

An ObJGCt of the invention 1s to provlde' an improved magazlne and meansfor detachably connecting the magazme to a' -gun'in a reliable manner toprevent accidental un locking of the magazine when the gun is fired.

A further object of the invention is to provide detachable magazineattachmentsthat shall be so constructed that a hunter wearing thickgloves may easily unlock and remove a magazine and replace it by anotherloaded magazine without necessitating the removal of his loves.

A further obJect of the invention is to provide a detachable magazinethat shall be free from projections that would be 1"b1e to catch in thegarments' 'ftiffthe hunter when handling the magazines or placingthemi'nto' his pockets or into the gun.

. .A still further object is-to provide improved triggerplate thatshallbe SOIQOHQ.

structed as to not only detachabl the magazine with the gun, to guardthe I I injury durin ugh usage while'hu or under othencircumstance's,whichimagazine and connecting means shall be relatively simple inconstruction, 'afiord positive locking means and be durable andeconomical in use. i The invention consists in an improved trigger platefor guns, provided with a transversely operating locking bolt and alsoin; Fig. 2";

. connect magazine r'er'riovably secured in the trigger plat'eby meansof the locking bolt.

The'invention consists also in .the various novelparts and combinationsand arrangements'ofparts as hereinafter particularly described andclaimed.

Referri'ng to the drawings, Figure l is a fragmentary side elevation ofan auto-loading rifle'of' Well known type provided with the improvedmagazine I and attachments therefor; Fig. 2, a longitudinal sectionalelevation of Fig. l on an enlarged scale; Fig. 3, a'fperspectiveview ofthe follower for the'niagazine'; Fig. 4, a'fr'ag'mentary sectionapproxlmately'on the plane of the line A Av Fig.' 5, a transversesection ap-' proximately on the line B B in Fig. 2; Fig. 6,'fa centralsection similar to Fig. 2 omitting the magazine; Fig. 7, atop planof theim-' proved trigger plate; Fig. 8, a section of the t'rigger plate onthe line C C in Fig. 7; Fig. 9' afront elevation of the trigger plate; 1Fig. 10-, ase'ction of'the trigger plate on the line D D in Fig. 8; Fig.11, a section approximately on the line E E in Fig. 1; Fig. 12', acentral section of a part of the locking bolt; Fig.13, a fragmentarysection of the trigger plate Fig'. 14, a fragmentary sidee'levatio-rr ofthe trigger plate; "Fig. 15, a perspective view of the improved portionsof the trigger plate provided with the improved magazine lock;'Fig. 16,a perspective" view of the m'a-inlpart of the improved lockbo'lt, andFig. I7, a perspective view of the improved magazine.

Inthe drawings similar reference characters throughout the'severalfigures thereof indicate corresponding elements or features ofconstruction herein referred to.

In order that a clear understanding of structure and function of theinvention iniajy be had,'the same'is conveniently shown 'a's'a" pliedtoa" popular type of rifle used ofthe rifle comprising'a barrel lmovablein a jacket or fore-"sto'ck2 havin 8 lug 3 that is det-achablsecuredjto' a lock frame 4 by e lock frame has a receiver 6 manic.edfandhasa breech bolt 8 movably mounted therein. The rifie referred tohas originally a; trigger plate that is r'e'mov'ably secured in theunder portion of the" ltuzk frame and connected with the undersideofthebutt-stock, 110

' largelyfor hunting purposes, familiar parts 1 a b hemian is movablymount- 10 said trigger plate being omitted in the drawings and replacedby the improved trigger plate and other elements of the invent-ion.

As preferably constructed the invention comprises a trigger plate 9which in contour is similar to and is applied in place of the triggerplate heretofore used, and it has a trigger guard 10 and supports ahammer 11 and a trigger 12. The trigger plate has an opening therein sothat structurally two side plates 13 and 14 are formed forwardly of thetrigger guard, the hammer being arranged between the plates. Two sidebars 15 and 16 extend forwardly from the outer portions of the platesand they are somewhat thinner than the plates and have extensions 17.and 18 respectively, that are continuous with the plates 13 and 14.Forwardly facing shoulders constituting straight guides 19 and 20 areformed on the-ends of the plates at a short distance forward of thetrigger guard, theguides extending obliquely to the plane of the top ofthe trigger plate which is. seated in a'suitable recess in the lockframe .4. The side bars 15 and 16 have an integral The lower edges ofthe side bars and their extensions are curved as arches so as to leavethe middle portions of the magazine accessible, the side bars 15 and 16having also extensions 24 and 25 that areintegral wit-h the upwardlyextending portion of the end bar 21. The exterior of the end bar 21,beingthe forward end of the trigger plate, is provided with tongues 26that extend into suitable recesses in the frame 4, the trigger platebeing suitably fitted into an opening in the frame. The upper end or topof the end bar 21 has a projecting lug 27 thereon that extends onto asuitable shoulder formed in the frame 4. The upper end or top of the bar21 is adjacent the rear end of the barrel 1 and has an inclined guide 28thereon for guiding the nose of the cartridges upwardly into the barrel,and at opposite sides of the guide the upper end of the bar 21 has twoinwardly extending stop projections 29 and 30thereon for limiting theinward or upward movement of the magazine.

The side plate 13 has a cylindrical guide bore 31 therein and the plate14 has a relatively smaller guide bore 32 therein in alinement with thebore 31, the guide bores being relatively close to the guides 19 and 20respectively, and the extension 18 of the side bar 16 has a guideway '33therein adjacent to the guide 20, a recess 34 being formed in the outerside of the plate 14 and extending from the guide bore 32 to theguideway 33.

' A novel locking bolt is provided which comprises a main bar 35 that isfitted movably in the guide bore 32 and has a lateral arm 36 on one endthereof that normally extends in the recess 34 and has for a catch orslide bar 37 thereon that extends through the into the bore 31. Thelocking bolt comprises also a cylinder 40 having a head 41 and is fittedslidingly intothe bore 31 and has internal screw-threads 42 which engagethe screw-threads 39, the cylinder head having a flange 43 to be movedinto contact with the plate 13 for limiting the movement of the lockingbolt when retracting the catch. The head 41 preferably has a slot 44therein to receive a screwdriver. A spring 45 is coiled about the bar 35and is seated against the inner end of the cylinder within the bore 31and is seated also against the innerside of the plate 14, and the springhas sufficient tension to normally hold the catch 37 in normal positionprojected through the guideway 33.

A box-magazine comprises two side plates 46 and 47 a rounded forward end48, and a relatively thick rear tend 49 in the upper end of. which is aslot 50, the side plates extending upward slightly beyond the plane ofthe top of the ends of the magazine and having curved lip portions 51and 52 respectlvely extending over each toward the other adjacent to therear end and also similarly curved portions 53 vand 54 adjacent to theforward end, the latter serving as stops for the follower, the magazinehaving also a bottom 55. The inner side of the rear end 49 has alongitudinal guide groove 56 therein. The forward portions pf the sideplates 46 and 47 are provided on their inner sides with vertical guideribs 57 and 58 respectively that are parallel to the rear end 49. The

rear end portion of the magazine is suitably the stops 29 and 30. Asuitable follower 60 is placed in the magazine and has a guide lip 61 onits rear end that slides against the end 49 and has also a tongue62 thatis'guided in.

The opposite end portion 'of the groove 56. V the follower has notches63 and 64 in opposite edges thereof that receive the guide ribs 57 and58 respectively. A suitable spring 65 is supported on the bottom 55 andyieldingly supports the follower 60 forforcing the cartridges out of themagazine to be carried into magazine when being inserted or withdrawn]In practical use the gun barrel may contain one cartridge and asdesigned the magazine may contain five cartridges, the uppermost one ofthose in the magazine being in contact with the lips 51 and 52 untilmoved therefrom by the push bars 67 and 68 into the barrel to replace anejected shell. The operations incidental to firing the gun are wellknown and require no further description. When the magazine becomesempty or when it is desired to detach it from the gun it is onlynecessary to press the head 41 slightly and thereby retract the catch 37from the shoulder 59, and then withdraw the magazine and release thehead.

In order to apply the magazine to the gunthe rounded forward end 48 isslightly inserted in the guideway formed by the end 21 and theextensions 22 and 23 of the trigger plate, and then the rear end portionof the magazine between the guiding extensions 17 and 18, the curvedlips 51 and 52 facilitating the latter movement, the rear end beingfurther pushed inwardly and tilting the magazine slightly to bring therear end 4:9 parallel with the guides 19 and 20, after which slightlymore force is applied and the magazine pushed in until stopped,

the'lip 52 in its passage causing the catch 37 to be retracted until themagazine is seated in normal position, when the catch enters the recessand engages the shoulder 59. It will be understood that in case thespring 45 becomes weak or fractured dur- 1 look frame, and a triggerplate secured to the frame and comprising-a trigger guard, two side'plates extending forward from the guard and constituting magazineguidesrespectively, two side bars extending forward om the outer sides of theside plates and having a forward magazine ard and guide thereon thatextends opposite the two guides and upward into the lock frame anddownward beyond the plane of the'side bars, the guard extending alsodownward from the outer sides of the side bar s,
